Abstract

Abstract: The field trials of five different pesticides for the control of rice blast were studied in order to provide better control agents for the production of rice blast. The results showed that 9% pyraclostrobin CS （Daoqing） of 900 mL/hm² had best prevention and 75% tricyclazole （Haoyan） WP of 450 g/hm² and 20% tricyclazole WP of 1 500 g/hm² had better prevention on rice leaf blast and spike blast.

Key words: rice blast, rice, pesticides, prevention
